Search All Fields Not Providing Expected Results (lowercase vs. uppercase letters)

[jamiers99]

I wasn't sure if I was supposed to link this to closed ticket #1770

Technical details regarding my environment

• YOURLS version: 1.7.2
  • Plugins enabled: 404 Not Found. Allow Forward Slashes in Short URLs, Don't encode/decode, Short URL so what
• PHP version: 5.6.30
• Any other useful information depending on context (server OS & version, MySQL version, browser version, …): MySQL 5.5.51-38.2, Chrome 64.0.3282.186

Bug description

What is the current behavior?
I notice that when I use the search at the bottom of the page, that Title is not being searched for upper OR lower case letters. I currently have 1.7.2 with plugins noted above:

I have two items in my entries for titles:

• Bulk Distribution Operations ILT
• Bulk Distribution Fundamentals WBT
  When searching for 'bulk' no entries appear. When searching for 'Bulk' both entries appear.

But... I have dozens of entries that show WBT in the title:
blah blah WBT
blah2 WBT
Blah Blah Blah3 WBT
When searching 'wbt' they appear, when searching 'WBT' they appear, but when searching 'Wbt' or 'wBt' they do not appear.

This is a bug because… searching is not consistent with expected behavior of user. Lower case letters are typically used in search engine queries.

Reproducible bug summary

1. Type word into search box
2. results not expected

if url contains char "%", the result is wrong too!

It doesn't appear as this has been fixed in 1.7.3. Is this on the roadmap to be fixed?
